Does a stolen antique car hold the clue to a secret fortune? Husband and wife treasure-hunting team Remi and Sam Fargo head to England to help Viscount Albert Payton recover a fortune that was lost a hundred years ago - along with the family's good name. It is believed this treasure was linked to the theft of a Rolls-Royce prototype called the Grey Ghost, which legendary detective Isaac Bell helped to recover, while the treasure itself remained missing. But then the Grey Ghost is stolen once again - this time from right under the noses of the investigating Fargos. And the Viscount vanishes too. It's up to Remi and Sam to solve the mystery, but now their lives are in serious danger...
